I carry every work day, back and forth to the office. I carry my Para Ordnance OPS (3-1/2" barrel .45 ACP) in an outside pocket of my briefcase, which I lay on the passenger seat within easy reach while I'm driving.
When I get to the office, I have to leave the pistol in the truck, because of a policy against weapons in the workplace. So as I walk through the parking garage to and from the truck, I'm unarmed.
Fortunately, our building is located in a pretty specific area where you'd be extremely unlikely to find any undesirables - much less would they be wandering around our parking garage. I've been in the garage in the wee hours (e.g., midnight or later) and it's completely abandoned. Of course, I would prefer to be able to have my .45 with me while walking from the stairwell door to the truck through the garage, but I'm actually not terribly concerned about not having it.
There are plenty of areas in the Richmond vicinity, though, where I definitely would not want to be without my .45 handy.
